Another fantastically busy week at Big Finish got off to an explosive start with the return of Indira Varma as Suzie Costello in Torchwood: Moving Target – available to buy and download now!

Written by Guy Adams, this time-locked thriller pushes Torchwood Three's most infamous agent to her limit, when she's forced to defend the innocent civilian Alex (Naomi McDonald) from a vicious alien onslaught. Sci-Fi Bulletin gave the story a 10/10, saying that 'Once again this incarnation of Torchwood proves that being adult does not have to mean gratuitous sex, violence and swearing, but can be about dark moral choices. Highly recommended.' Pick up your copy today on its own, or as part of a money-saving Torchwood: Series 2 subscription.

Tuesday saw the announcement of a second set of Dark Shadows short stories. Dark Shadows: Haunting Memories will include four new stories, including a tale by Angelique herself, Lara Parker, writing for Big Finish for the first time.

Another Sixties' classic returns to life this summer with The Avengers: The Lost Episodes Volume 6. Once again starring Julian Wadham and Anthony Howell as the eponymous investigators, the new volume finds the pair confronting extortionists, spies and industrial espionage.
